It all comes down to what comp your facing, for instance if your facing assa rogues or ferals, they are more than likely going to be tunneling you, so playing Dwarf would be the best in that scenario as you can use your racial to remove the bleeds. So i'd just say to you, play what ever you want to!

I play undead on my mage even though orc is probably overall better, but I find undead more appeasing to the eye so I play it and on 3k+cr no problem.
